2.10 sHielD gas

NOTE! Handle gas bottle with care. There is a risk for injury if gas bottle or bottle valve is damaged!

Use inert gases such as argon, helium or argon-helium mixture as shield gas for TIG welding. Make sure that the gas flow regulator is suitable for the gas type used. The flow rate is set according to the welding current, joint form and the size of the electrode. A suitable flow rate is normally 8 – 10 l/min. If the gas flow is not suitable the welded joint will be porous. Spark ignition becomes more difficult if the gas flow is too high. Contact your local Kemppi dealer for choosing gas and equipment.

2.10.1 installation of gas bottle

NOTE! Always fasten gas bottle properly in vertical position in a special holder on the wall or on a carriage. Remember to close gas bottle valve after having finished welding.

The following installation instructions are valid for most gas flow regulator types:1. Step aside and open the bottle valve (A) for a while to blow out possible impurities from the

bottle valve. Note! Watch out for the gas flow.2. Turn the press regulation screw (B) of the regulator until no spring pressure can be felt. 3. Close needle valve if there is one in the regulator.4. Install the regulator on bottle valve and tighten connecting nut (C) with a wrench.5. Install hose spindle (D) and jacket nut (E) into gas hose and tighten with hose clamp.6. Connect one end of the hose with the regulator and the other end with the power source.

Tighten the jacket nut.7. Open bottle valve slowly. Gas bottle pressure meter (F) shows the bottle pressure.

NOTE! Do not use the whole contents of the bottle. The bottle should be filled when the bottle pressure is 2 bar.8. Open needle valve if there is one in the regulator.9. Turn regulation screw (B) until hose pressure meter (G) shows the required flow (or pressure).

When regulating flow amount, the power source should be switched on and the gun switch pressed simultaneously.

Close bottle valve after having finished welding. If the machine will be out of use for a long time, unscrew the pressure regulation screw.

1. Dynamics (“arc” –9 … 0 … +9)You will see the numerical value corresponding to the MMA dynamics in the display. Factory setting for all electrode types is zero. You can change the value by turning the control knob. If numerical value is adjusted negative (-1...-9) the arc is softened, and the amount of spatter decreases when welding at the upper end of the recommended current range of the electrode. On the positive side (1...9) the arc is rough.

2. ignition pulse (Hot –9 … 0 … +9)You will see on the display the numerical value corresponding to the MMA ignition pulse. You can adjust the value by turning the control knob. A positive value corresponds to a more powerful pulse, with zero being the default setting.

2. Tig weldingSelect TIG welding by pressing the TIG button. You can change the current type by pressing the selection button again (AC, MIX, DC-, DC+). Selecting DC+ requires holding down the button. According to selected current mode you can adjust parametres by using QUICK SETUP -function. Quit from QUICK SETUP -function by pressing QUICK SETUP -button. At the same time you can see recommended diameter for electrode.

aC Tig (alternating current Tig)Intended for welding aluminium. You can adjust, for example, the balance and frequency of the alternating current with the QUICK SETUP and arrow buttons. The following welding parameters can be adjusted:

1. Balance (bal -50 … 0 %, factory setting –25 %)In AC welding the ratio of the positive and negative half waves is called the balance. It determines the heat input proportions to the base material and to the electrode.

effect of the balance adjustment:A positive balance value breaks up aluminium oxide more effectively but heats the electrode more than the workpiece (the tip blunts). A negative balance value increases heat generation and penetration in the base metal, while decreasing oxide break-up.If you wish to increase electrode temperature when welding with a blunt-headed electrode, adjust the balance in the positive direction, and if you wish to decrease electrode temperature when welding with a sharp electrode, adjust the balance correspondingly in the negative direction.At the factory setting, the electrode tip remains almost sharp.A sharp electrode allows welding with a narrower arc, achieving a narrower weld and deeper penetration than with a blunted electrode. Narrow welding is especially useful when welding a fillet weld.Welding with a blunted electrode produces a wide arc, which also widens the area of oxide break-up. Application areas include repair welding and casting.

2. Frequency (Fre 50 … 250 Hz, factory setting 60 Hz)Raising the frequency will make the arc slightly more stable and narrow, but it will increase the noise caused by arc.

3. selection of aC waveform, sine or square wave (sinus/square)The waveform affects the noise level and penetration of the arc. A sine waveform generates a lower noise level, while a square wave has better penetration (factory setting).

4. Hot start time for the 2T function (H2t 0.1 s…5.0 s, factory setting 1.0 s)Pre-heating timer for the 2T switch function. The workpiece can be pre-heated (Hot Start) with both AC and DC currents. The time set here remains in effect for DC TIG current types.

4. DC- (or DC+) (direct current)Hot Start time for the 2T function (H2t 0.1 s…5.0 s, factory setting 1.0 s). Can be seen only on the 2T function. You can see recommended diameter for electrode by pressing QUICK SETUP -button. Diameter depends on current adjustment.

HF/contact ignition in Tig welding (water fill)TIG arc can be started either with high frequency (HF) or with contact ignition. HF ignition is chosen by pressing the HF CONTACT button to turn on the HF light. If you use water-cooled torch you can fill it with water by pressing the HF CONTACT button for more than 2 seconds. The display reads ’COOLER’.

welding torch switch 2T function Gas flow starts when the torch switch is pressed. Welding starts, and the current will rise to the Hot Start current within the up-slope time, remain at that level for the set time (H2t) and then change to the welding current. The Hot Start function can be disabled and green panel light switches off when the Hot Start current is adjusted to 100 %. The current will then rise directly to the welding current level within the up-slope time. Release the torch switch, and the current starts to drop, and after the selected down-slope time the arc is broken. After this, the shield gas will flow for the time selected.

welding torch switch 4T functionGas flow starts when the torch switch is pressed. Release the torch switch. The ignition spark ignites the arc, and the current will rise to the Hot Start current within the up-slope time. You can switch from Hot Start current to welding current with a short press of the torch switch. You can disable the Hot Start function by adjusting the Hot Start current to 100 %. The current will then rise directly to the welding current level within the up-slope time. Press the torch switch down, and the welding continues. Release the torch switch, and the current starts to drop and after the selected down-slope time the arc is broken. After this, the shield gas will flow for the time selected.

remote controlIf you choose to adjust the welding current with a remote control unit you need to connect the unit and select the remote control selection button. The PANEL light switches off, and you can select the unit (R10, foot pedal control R11F, or torch control). The foot pedal control works only in 2T mode. Hold the remote control selection button (LO/HI) down to adjust the limits of the remote control’s adjustment range.

adjustment of parametersTo select TIG welding parameters you only need to use two buttons: arrow-left and arrow-right. Red panel light shows parameter you have chosen. Adjustment is done with the control knob. When pressing the RETURN button, adjustment of parameters goes straight to welding current. The display shows automatically numeric values and the units of the parameters. When you adjust the parameters, you can see the value on the numerical display. After 10 seconds, the display will return to the welding current.

4. MainTenanCe

NOTE! Watch out for mains voltage when handling electric cables!

Degree and circumstances of machine utilisation should be taken into consideration when planning product maintenance. Careful use and preventive maintenance help to avoid unnecessary production disturbances and breaks. Check the condition of the welding and connection cables daily. Do not use damaged cables.

4.1 regular MainTenanCe

4.1.1 every sixth months

NOTE! Disconnect the plug of the machine from the mains socket and wait for ca. 2 minutes (capacitor charge) before removing the casing plate.

The following maintenance operations should be carried out at least every sixth months:

• Electric connections of the machine - clean any oxidised parts and tighten any loose ones.

NOTE! You must know the correct tension torques before you start repairing the connections.• Clean the inner parts of the machine from dust and dirt e.g. with a soft brush and a

vacuum cleaner. Do not use compressed air because there is the danger that the dirt is packed even more tightly in the gaps of the cooling profiles. Do not use a pressure washer.

NOTE! Only an authorised electrician may repair the machine.

4.1.2 service contractKEMPPI service workshops make special service contracts with customers about regular maintenance. All parts are cleaned, checked and if necessary, repaired. Also the operation of welding machine is tested.
